The following description is directed to the specific forms of the invention illustrated in the drawings and is not intended to limit the scope of the invention itself which may be practiced in a wide variety of forms and arrangements.

mechanism Adverting herewith to the specific form of the invention illustrated in the drawings, in FIG. 1 is shown a textile finish applicator having a generally rectangular casing 10 provided with a generally rectangular platform 12 at the front thereof and formed integrally therewith. To a side wall 14 of the casing 10 there is mounted an L-shaped arm 16 having a pulley wheel 18 rotatably fixed at the distal end thereof. Mounted to a front wall 20 of the casing 10 is a tension device 22 having a wheel 24 axially centered thereon with a knurled nob 26 mounted adjacent said wheel 24 on the same axis, which nob is affixed to a threaded screw which permits the tightening of said nob 26 against the wheel 24 for for a purpose to be described more fully hereinafter. Adjacent the tension device 22 are wheels 28 and 30, which are respectively mounted axially to support arms 32 extending perpendicularly from the front wall 20 of the casing 10. Spaced apart from the wheel 32, a similar wheel 33 is similarly mounted to the front wall 20 of the casing 10. Intermediate the Wheels 32 and 33 and mounted to the front wall 20 of the casing 10 is a holder assembly 34 comprising a support bracket 36 having a circular opening 38 provided in the top portion thereof of dimension to receive a threaded shaft 40 having an unthreaded portion of wider diameter 42 at the top thereof and situated in the bore of the opening 38. Affixed to the top of the threaded shaft 40 is a knurled thumb screw 44 by means of which the shaft 40 may be turned manually. The shaft 40 extends into a threaded bore 46 provided for that purpose in a projecting segment 48 of a clamp 50, which projecting segment extends into the bracket 36 through an opening 52 in the front wall 54 thereof. The projecting segment 48 has a rear surface 56 which abuts the rear interior wall 58 of the bracket 36. Clamp is further provided with flanges 60 and 62 which abut the front wall 54 of the bracket 36. The clamp 50 further comprises an outer plate 64 which is secured to an inner plate 66 (formed integrally with the segment 43) by means of thumb screws 68 and 70 which may be turned manually to loosen the outer plate 64 from the inner plate 66. symmetrically formed rubber-lined indentations 72 and 74 are correspondingly positioned in the inner and outer plates 64 and 66 respectively, for the accommodation of one arm 75 of an L-shaped moistener tube 76. The end 78 of the arm 75 is provided with a V-shaped indentation 80 for a purpose to be described hereinafter. The L-shaped tube 76 is provided with a capillary opening 82 which extends through the center thereof from the end 78 to the opposite end 84 thereof. Spaced apart from the holder assembly 34 and above the platform 12 is a cylindrical drying drum 86 which is mounted axially to a shaft 88 of an electric motor 90 of variable speed situated within the casing 10. The motor 90 may be energized by a switch 92 mounted to the front wall 20 of the casing 10. Intermediate the drying drum 86 and the holder assembly 34 a canted roll 94 is mounted to the front wall 20 of the casing 10 in the conventional manner.

' I Extending from a side 96 of the platform 12 is an arm 98 having a yarn guide eye 100 afiixed to the distal end thereof through which passes a yarn Y upwardly to wheel 18 over which the yarn passes to run in a generally horizontal direction to pass beneath the wheel 28, over the wheel 24 and beneath the wheel 30. From the Wheel 30 the yarn Y passes through the V-shaped indentation 80 of of the tube 76 and runs thence beneath the wheel 33 whence it passes to the drying drum 86. The yarn Y winds around the drying drum 86 and returns to pass around the canted roll 94, repeating the passage around drum 86 and roll 94 until the yarn Y finally passes from 0 the machine to a lead-01f wheel 102 and thence upwardly to a wind-up reel 104.

Mounted to the top surface of the platform 12 and spaced apart from the front wall 20 of the casing is a pumping mechanism 106 comprising a frame 107 at one end of which there is disposed a holder structure 108 having side walls 110 and 112 and partially open at the opposite ends thereof to provide an indentation or'trough 114 for the reception of a removable cylinder 116, which is preferably made of glass and provided with graduated markings 118. Mounted to the wall110 is an L-shaped bracket 120 which is fitted with a thumb screw 122 which may be adjusted to hold the cylinder 116 immovably in the trough 114. The cylinder 116 is open at one end 124 thereof and is provided in the opposite end 126 with a retaining wall having an opening disposed centrally therein which communicates with a tubular section 128 of greatly reduced diameter adapted to receive a rubber or plastic tube 130 over the free end thereof. Tube 130 is aflixed at its opposite end over the end 84 of the moistener tube 76.

Through the open end 124 of the cylinder 116 is re-.

ceived a plunger or piston 132 of appropriate dimension to fit snugly Within the cylinder 116 and to move reciprocally therein. At the free end of the piston 132 is formed a shoulder 134 which abuts a drive plate 136 having sleeves 138 and 139 formed integrally in the opposite ends thereof, which sleeves are slidably mounted on longitudinally extending rods 140 and 142, the ends of which are immovably fixed to the opposite walls of the frame 107. Rotatably secured in the end wall 144 of the holder structure 108 is a worm shaft 146 having the opposite end thereof immovably aflixed in a shoulder 148 formed integrally with a gear 150. The gear 150 may be turned by a drive gear 152 axially mounted to a shaft 153 of a detachable motor of constant speed 154. The motor 154 is secured to a support plate 156 mounted on the frame 107.

Aflixed to the drive plate 136 is a pincer clamp element having arms 158 and 160 each of which is threaded at the lower extremity thereof to form a pair of jaws 161 adapted to engage the worm shaft 146, as shown in FIG. 1. The arms 158 and 160 are each pivotably secured to the drive plate 136 so that the lower extremities thereof may be opened or closed by turning a rotatable lug 162 afiiXed to a thumb screw 164 provided for that purpose.

In operation of the textile finish applicator as provided in accordance with this invention, yarn Y is threaded through the apparatus as previously described, entering the machine through yarn guide eye 100 and leaving the machine as it winds from the drying drum 86 to pass to the lead-off wheel 102. The motor 90 is actuated by the switch 92 and preliminarily adjusted to the desired speed. The tubular moistener 76 is secured into the holder assembly 34 by inserting the arm 75 into position between the plates 64 and 66 in the rubber-lined. indentations .72 and 74 provided for that purpose and thereafter tightening said screw 68 and 70 to hold the moistener 76 firmly in place in the clamp 50. Thereafter, the flexible tube 130 is fitted over the end 84 of the moistener tube 76. The

height of the moistener tube is adjusted by means of the nob 44 by turning the shaft 40 to raise or lower the clamp 50 relative to the yarn Y so that the lip of the moistener tube 76 formed at the end 78 of the arm 75 thereof engages the yarn Y to permit the yarn to pass through indentation 80. Tension is applied to the yarn through the tension device 22 by tightening .or loosening the nob 26 thereof which causes the wheel 24 over which the yarn Y passes to rotate more or less freely as desired. When preliminary adjustment of the yarn speed and yarn tension has been made as described, cylinder 116 is provided with textile treating fluid and the plunger 132 inserted into the open end 124 thereof, after which the cylinder 116 is placed in the trough 114 and secured therein by means of the thumb screw 122. The tubular section 128 of the cylinder 116 is secured in the opposite end of the flexible tube 130. The drive plate 136 is then brought forward to abut shoulder 134 of the plunger 132 and the threaded jaws 161 of the clamp element of the drive plate 136 are closed by spreading apart the arms 158 and 160 by means of the rotatable lug 162. With the jaws 161 closed, the clamp element is engaged with the worm shaft 146. The detachable motor 154 is then secured to the plate 156 so that the drive gear 152 engages gear 150,

after which, upon actuation of the motor, gear 150 turns with a constant predetermined speed to rotate the worm shaft 146 thereby moving the drive plate 136 toward the cylinder 116 to drive the plunger 132- thereinto .at a

uniform rate of speed. Plunger 132 displaces a uniform volume of treating fluid from the cylinder 116 at a prededetermined rate which forces treating fluid through the tubular section 128 into the flexible tube 130 and thence into the moistener tube 76 where the fluid moistens the yarn at the end 78 thereof as the yarn passes through the.

indentation 80. After the desired flow of treating fluid has been established, the yarn speed or yarn tension may be readjusted, if desired, to assure uniform absorption of thetreating fluid by the running yarn. Contrariwise, with the anism, a motor of variable speed may be used instead. Itv has been found, however, that in practice, detachable motors of constant speed are preferable because they give a more uniform flow of treating fluid by reason of the constancy of the speed of each individual motor.

It will be evident too that the volume of treating fluid which it is desired to apply to a given length of yarn may be varied by substituting a smaller or larger cylinder in the place of the cylinder 11.6.

From the foregoing it will be evident that it is an important advantage of the invention that by means of the precisely controlled pump mechanism a predetermined flow of treating fluid to the textile material may be obtained. Moreover, the flow of treating fluid to the moistening tube of the apparatus may be adjusted as desired in order to provide exactly the right amount of treating fluid to the yarn so that the treating fluid applied to the yarn is completely absorbed thereby without any excess application of fluid to the yarn.

Another important advantage of the invention resides in the fact that the amount of treating .fluid used with a given length of yarn may be precisely measured and predetermined.

Although this invention has been disclosed with reference to specific forms and embodiments thereof, it will be evident that a great number of variations may be made without departing from the spirit and scope of this invention. For example, parts may be reversed, equivalent elements may be substituted for those specifically disclosed and certain features of the invention may be used independently of other features, all without departing from the spirit and scope of this invention as defined in the appended claims.
